### 4.4 INTERNET GROUP MANAGEMENT PROTOCOL - IGMP

IGMP [INTERNET:4] is a protocol used between hosts and multicast routers on a single physical network to establish hosts' membership in particular multicast groups. Multicast routers use this information, in conjunction with a multicast routing protocol, to support IP multicast forwarding across the Internet.

A router SHOULD implement the host part of IGMP.
